Cas·i·mir effect

 (kăz′ə-mîr′)
n.
The effect of a net attractive force between objects in a vacuum, caused by the reduction of vacuum pressure in the space between the objects, where the wavelengths of vacuum fluctuations are more limited than in the space around the objects.

[After Hendrik Casimir (1909-2000), Dutch physicist who predicted its existence in collaboration with Dirk Polder (1919-2001), Dutch physicist.]

Place a mirror to face a mirror and you will glimpse eternity, and this arrangement forms the basis of the Fabry-Perot interferometer, a device used in telecommunications and astronomy - and it may also be used in a future time machine because of the "Casimir Effect" - the production of negative quantum energy between perfectly parallel mirrors - and this energy could be used to inflate wormholes to open up the past and future.

Yes, zero-point energy is real, as the Casimir effect and the Lamb shift bear out; but basic thermodynamics precludes extracting arbitrarily large "free energy" from the vacuum.
The phenomenon, known as the dynamical Casimir effect, has now been observed for the first time in a brilliant experiment conducted by the Chalmers scientists.
